To all dilwmitma concern: 7

Be it known that Ham Impnmn MARIE Josnrn Barman, engineer, a citi en of the Republic of France, residing. at 82 Rue Curial, Paris, France, have invented new and useful Im rovements inand Relatin to 00-- culting Lights, of which the following is a specification.

ing lig t designed to transmit to lon distances luminous signals of any kin and, more particularly, for transmitting all the si als of the Morse code.

' his lantern comprises, as an essential'element, a device which ermits of causing a succession of flashes an periods of darkness in such a way as to affect all the desired signals automatically. ,1

The/accompanying drawing shows purely by way-of example an occulting light constructed according to the invention.

The apparatus consists essentially of a lens of the usual t e mounted in a weatherproof lantern. At t e focus-of the lens is arranged a suitable source of light, for instance -a lamp a (Fig. 1) with orizontal carbons.

The device serving to move the source of light a can be mounted for example on three .of the beam or to giveit passage. The shutters can be connected to a common sector or quadrant 0 which pivots about an ans 0 and can be actuated by any suitable motive power.

In the example shown here, this drive is.ob-

tained irom an electro-magnetic device.

This latter consists essentially oftwo electroma ets d, e which areexcited. individually an impart to the quadrant c a movementfirst in one direction and then in the other, according as to whether it isdesired to cause the opening or closing of the shuttersia. The cores ofthese clectro-magnets are connected The present invention relates to an occult- I Fig. 5is a detail modified formof the cam 6 is a detail sectional view ofthe trans- Specification of Letters Patent.

by rods (1, e. to an arm of forming a part of the quadrant c.

The exciting current, generated'by the dynamo m ior exam le, can be sup lied to the electro-magnets e by any suita le distributing means whic will present itself to the engineer. The followin given merely as an example, is a description of a device fu fillin the conditions laid down. f

This evice consists essentially ofa disk f mounted onan axis f and having its peri hery shaped to form cams f, 'f. This isk vreceives from the dynamo m by the wires m,-

m' a'rotar'y movement from a motor for instance an electmc motor 9, a sultable s eed .reducing device 71. being interposed an in-' cluding a worm I). on the shaft 9 of the motor, which worm h meshes with a worm wheel h fixed upon the shaft f which rotates the disk f. A bent lever 11 ivots about i and plays the part of a -distri uter; it is held constantl in contact with the periphery of the disk bymeans of a spring a" and serves by the aid of its contact 1? to close the circuit, on .the onehand to the electro-magnet d through the terminal j and the wires m. m and, on the other hand, the circuit for the electro-magnet e through the terminal is and The distributer i is,connected to one of the poles of the dynamo m by a wire mf; it may assume three positions; one sends the current to the electro-inagnet d, the other sends the current to the electro-magnet e,

while in the third position, neither of the electro-ma ets is excited. I

It should be pointed out that the electroma ets only receive current at the moment of 5 1 s opening and shutting of the shutters .b and, a point which is very important, only at the instant at which the shutters are operated, so that any over-heating of these electro-magnets is avoided.

The three positions of the distributer i are controlled by the disk f, the number and sha of the cams thereon being varied accor ing to the different characters of the Morse or other code which it is desired to emit. A single disk effects the opening and .closing of the shutters, and this disk f can be rapidl and easily replaced by another, such as shown.in Fig. 5, which gives a different character to the signal incident to an increased number of cams f.

A handle Z enables one to manipulate the shutters .by'hand and to make any other desired si als indeplendently of those.
